Abstract

Impatiens is a diverse genus within the Balsaminaceae family, comprising over 1,120 species. The northern Gayo Plateau of Sumatra, an island in Southeast Asia, is renowned for its rich Impatiens diversity. In this paper, we described and illustrated a new species named Impatiens bungeusing from this area. This species is most similar to Impatiens vitellina Grey-Wilson but differs in having the distinct abaxial leaf venation in a dry state (vs obscure), lateral sepals falcate-oblong (vs narrowly lanceolate), lower sepals with U-shaped spur (vs straight), broadly ovate dorsal petal (vs ovate), and ovate sub-rhomboidal upper lateral united petals (vs oblong). This discovery brings the total number of known Impatiens species in Sumatra to forty-eight.

Abstract

The Lower Cretaceous Wealden Supergroup of southern England yields a diverse assemblage of theropod dinosaurs, its taxa being represented by fragments in addition to some of the most informative associated skeletons of the European Mesozoic. Spinosaurids, neovenatorid allosauroids, tyrannosauroids and dromaeosaurids are among reported Wealden Supergroup clades. However, the majority of relevant specimens are from the Barremian Upper Weald Clay and Wessex formations, and theropod diversity in the older Berriasian–Valanginian Hastings Group has remained poorly known, the fragmentary specimens reported thus far remaining enigmatic both in terms of phylogenetic affinities and sometimes provenance. A better understanding would be welcome given the paucity of Berriasian–Valanginian dinosaurs worldwide. Here, we describe an assemblage of Hastings Group theropod teeth from the Valanginian Wadhurst Clay Formation, mostly collected from the Ashdown Brickworks locality near Bexhill, East Sussex. These teeth were assessed using phylogenetic, discriminant and machine learning analyses and were found to include members of Spinosauridae, Tyrannosauroidea and Dromaeosauridae, in addition to others that remain of uncertain affinity within Coelurosauria. The taxa appear distinct from those already known from Wealden Supergroup strata: the spinosaurid cannot be referred to Baryonyx or the tyrannosauroid to Eotyrannus, for example, but we have not named new taxa at this time. Combined with other findings in the Wadhurst Clay Formation, our study indicates that Valanginian theropod diversity was comparable to that of younger Wealden Supergroup units, implying that the ‘characteristic’ theropod components of Wealden faunas were established early in the deposition of this famous geological succession.

Abstract

A new species of pseudionine parasite is described from the deep-sea shrimp Notostomus gibbosus A. Milne-Edwards, 1881, collected in the Gulf of Mexico, the first record of a bopyrid parasitizing any member of the family Acanthephyridae Spence Bate, 1888. Morphological and molecular data are provided to support the inclusion of the new species and 12 other branchial ectoparasites of caridean shrimps in the genus Cryptione Hansen, 1897 that is resurrected herein. Cryptione is sister to the genus Pseudione sensu stricto, ectoparasites of axiid and callianassid shrimps as well as nephropid lobsters. The new species Cryptione grandis can be distinguished from its closest congeners including C. parviramus (Adkison, 1988) from the Gulf of Mexico by several female and male characters. The epicaridium larvae of C. grandis were examined with scanning electron microscopy (SEM), only the second description of this stage for any species in the genus. A table listing all species in Cryptione and taxonomic notes on some species are provided.

   DOI: 10.3897/BDJ.12.e139425

Abstract

Background: Anorthoa Berio, 1980 is a genus within the subfamily Hadeninae . This genus has a close relationship with the rama species complex of the genus Harutaeographa. It comprises three species groups: the munda-group, the angustipennis-group and the rubrocinerea-group. The species Anorthoa changi Ronkay & Ronkay, 2001 from Taiwan Island belongs to the rubrocinerea-group.

New information: A new species related to Anorthoa changi Ronkay & Ronkay, 2001, is described from Wuyishan National Park, China. The new species can be distinguished from its sister species by its larger size and some differences in the genitalia. Now, the number of species in the genus Anorthoa is increased to eleven.

Abstract 

Phellodon is a globally distributed genus of stipitate hydnoid fungi recognised by a white spore print and an ectomycorrhizal life strategy. In Europe, many Phellodon species have declining populations and are used as indicators of forests with high conservation values. However, their use in this context and the correct assessment of their extinction risk, according to IUCN guidelines, are currently hampered by inconsistent name usage and unclear species delimitations, primarily within the species complexes of P. melaleucus, P. niger and P. tomentosus. We analysed 286 ITS sequences of Phellodon, of which 51 were also analysed in conjunction with the corresponding LSU regions. This work included 102 newly sequenced collections, primarily sourced from Sweden and the UK. Our phylogenetic results show that four species are new to science and hence we formally describe P. castaneoleucus within the P. melaleucus morphological complex, P. aquiloniniger and P. frondosoniger within the P. niger complex and P. dititomentosus as a sister species to P. tomentosus. The combination P. melilotinus is made to accommodate an additional, previously described, species that belongs in the P. niger complex. We designate lectotypes and epitypes for P. melaleucus, P. niger and P. tomentosus as well as an epitype for P. melilotinus. Phellodon ellisianus is recorded as new to Europe and the ecological amplitude of P. secretus and P. violaceus is revealed to be wider than previously believed. We provide a key to all 13 species currently known in Europe and assign them to three habitat-based assemblages based on data from the Nordic countries and the UK. We hope this will facilitate the assessment of such habitats for legal protection and other conservation-related actions.

Abstract

Fissure fill deposits from the Late Triassic to Early Jurassic of England and Wales preserve a diverse small tetrapod fauna including procolophonids, an important group of Permian and Triassic parareptiles that radiated across Pangaea following the end-Permian extinction event. Procolophonids are currently known from two fissure fill sites: incomplete and isolated remains from Ruthin Quarry (Wales) and type and referred material of Hwiccewyrm trispiculum from Cromhall Quarry (southwest England). The age of the Cromhall fissure deposits has been debated but recent radiometric dating suggests a Carnian age for at least some of the fossil assemblages. Here, we present material from several fissure assemblages at Cromhall, which are interpreted as stratigraphically older than the assemblage that yielded Hwiccewyrm. We describe a new species of leptopleuronine procolophonid based on partial remains with unique tooth morphology. Threordatoth chasmatos gen. et sp. nov. is characterized by maxillae with a reduced number of complex tricuspid teeth along with dentaries that bear labiolingually compressed monocuspid teeth and in some cases have a peculiar edentulous tip. These distinct tooth morphologies occlude closely, perhaps facilitated by a flexible dentary symphyseal connection. This unique combination of characters may suggest a high degree of oral food processing of a mode unlike other procolophonids, occurring among the broader leptopleuronine adaptation towards diets of high-fibre herbivory/omnivory and insectivory. Phylogenetic analysis places the remains of Threordatoth as a derived leptopleuronine, sister taxon to Hwiccewyrm, in a clade with taxa including Soturnia, Hypsognathus, Libognathus and two unnamed leptopleuronines from the southwest USA.

 A, lateral; B, medial; C, ventral; D, dorsal view.

Genus Threordatoth nov.

 

Derivation of name: The genus name is derived from Old English and recognizes the tricuspid nature of the maxillary teeth of this taxon: þrēo meaning ‘three’ (undeclined) in the Mercian dialect; orda meaning ‘points’, or ‘spear points’; and tōþ meaning ‘tooth’.

 

Threordatoth chasmatos sp. nov.

Derivation of name: The species name is derived from Greek: χάσμα meaning ‘yawning chasm’, or ‘fissure’, referring to the fissures in which Threordatoth and numerous other taxa are preserved.

Diagnosis Distinguished from other procolophonids by the following combination of features: low maxillary tooth count (three or four); maxillary crowns are triangular in occlusal view, being strongly mesiodistally expanded at the labial margin (best developed in tooth 2); distal margins of the maxillary crowns are concave in occlusal view; maxillary crowns are tricuspid, with two clearly separated labial cusps; distolabial cusp of maxillary crowns is enlarged relative to mesiolabial cusp; two foramina on lateral surface of the maxilla, the anterior foramen being larger and positioned at the mid-height of the maxilla above the mesiolabial cusp of the second maxillary tooth, and the posterior foramen being positioned above the space between the second and third maxillary teeth and closer to the ventral margin.

Life reconstruction of Threordatoth chasmatos gen. et sp. nov. among the fissures of Carnian–Norian southwest England, based in part upon aspects of the anatomy of the closely related Hwiccewyrm.

[Botany • 2024] Cladopus yangjiangensis (Podostemaceae) • A New Species from Guangdong, South China, redefining the phylogenetic relationships within Cladopus

DOI: doi.org/10.3897/phytokeys.249.140342 

Abstract

This paper introduces Cladopus yangjiangensis, a newly identified species that enriches our understanding of the diversity of the Podostemaceae in East Asia. Distinctive in its morphological traits, this species is characterized by the region’s longest flowering shoots and exhibits a high number of elongated leaves per cluster, along with relatively slender roots. Phylogenetic analyses using Maximum Likelihood and Bayesian Inference methods on plastome and matK sequences confirm C. yangjiangensis as a distinct species. It forms a clade with C. fukienensis, its closest relative, together branching off from C. austrosinensis. The plastome of C. yangjiangensis is 132,818 bp in length, comprising two inverted repeat regions of 20,881 bp, which are separated by large and small single-copy regions of 78,713 and 12,343 bp, respectively. Genetic analysis reveals the extensive loss of the ycf1 and ycf2 genes in the chloroplast genome, a trait common to the Podostemaceae, suggesting adaptations to environmental conditions or gene transfers to nuclear or mitochondrial genomes. This study improves the clarity of phylogenetic relationships in previous studies and underscores the importance of continued taxonomic and phylogenetic research.

Diagnosis: Cladopus yangjiangensis shares certain similarities with C. fukienensis and C. austrosinensis, such as comparable ovary lengths, and analogous stigma and capsule shapes. However, it is distinguished by several unique traits. The leaves of C. yangjiangensis are markedly elongated, measuring 18.7–26.7 mm, which is substantially longer than those of C. fukienensis (1.3–5.0 mm) and C. austrosinensis (up to 6 mm). The flowering shoots of C. yangjiangensis also exceed those of other two species, ranging from 4.2 to 13.1 mm, compared to 3.5–6.0 mm in C. fukienensis and 1.6–3.5 mm in C. austrosinensis. Additionally, C. yangjiangensis produces a greater number of bracts, with counts ranging from 20 to 54, in contrast to 12–36 in C. fukienensis and 8–14 in C. austrosinensis. Finally, the root width of C. yangjiangensis is notably narrower, at about 0.4 mm, compared to 0.4–1.3 mm in C. fukienensis and 0.5–1.3 mm in C. austrosinensis (Table 3).

Etymology: The epithet yangjiangensis (阳江) refers to Yangjiang City, Guangdong Province, South China, where this new species was found.

Abstract

Based on morphological observations, molecular phylogenetic analyses and literature consultations, a new species of Gesneriaceae, Petrocodon mirus, is described and illustrated here. This new species exhibits morphological similarity with P. pulchriflorus and P. hechiensis, but is easily distinguished from the latter two by its slightly leathery leaf blade, liner to ligulate-oblong lip lobes, and shorter tube with constriction at middle. In addition, the new species differs from P. pulchriflorus by its reflexed adaxial lip lobes, and from P. hechiensis by its included stamen and pistil. However, the stigma of P. mirus is much similar to the chiritoid stigma diagnostic for Chirita Buch.-Ham. ex Don (now mostly included in Primulina); based on this observation a new hypothesis for the evolution of the chiritoid stigma is proposed.

It is distinguished by the presence of a large suprapectoral flap above the pectoral fin, and its unique lip morphology. The lower lip has a continuous anterior edge, and its median part has 8–10 ridges on each side, radiating at the anterior extremity, across the whole lip, resulting in a crenulated inner edge of the lip. 

Key words. Cobitoidei, Nemacheilidae, Schistura, Borneo, stone loach

[Mollusca • 2024] Fissidentalium aurae • A New Species of Fissidentalium (Scaphopoda: Dentaliidae) in association with an actinostolid Anemone from the abyssal Labrador Sea

 

 Fissidentalium aurae

 Linse & Neuhaus, 2024 

DOI: doi.org/10.1007/s12526-024-01481-1  

Abstract

The benthic biodiversity of the abyssal Labrador Sea was investigated using Agassiz trawl and in situ imagery. A megafaunal scaphopod associated with an epizoic anemone was recovered from soft sediments. Morphological and molecular investigations revealed the scaphopod to be an undescribed species in the dentaliid genus Fissidentalium P. Fischer, 1885. The new scaphopod species is characterised by a large size for the genus, is moderately curved, with numerous narrow, longitudinal ribs (60 ribs at 11 mm diameter ventral aperture), a dentaliid radula, and is described herein as Fissidentalium aurae sp. nov. The new species shows a close genetic relationship to congeners of Fissidentalium and separates from the sister genera Dentalium Linnaeus, 1758 and Antalis H. Adams & A. Adams, 1854. Genetic COI barcoding of the epizoic anemone suggests the species is a member of the family Actinostolidae Carlgren, 1932. The discovered association of a burrowing scaphopod with an epifaunal anemone at abyssal depth is a new record for the region and is indicative of how little is known about symbioses in the deep sea.

Class Scaphopoda Bronn, 1862

Order Dentaliida Starobogatov, 1974

Family Dentaliidae Children, 1834

Genus Fissidentalium P. Fischer, 1885

Type species: Dentalium ergasticum P. Fischer, 1883: 275–277; 

accepted as Fissidentalium capillosum (Jeffreys, 1877) type by monotypy.

Fissidentalium aurae sp. nov.

Diagnosis: A large-sized, over 60 mm in length and 10 mm in ventral aperture width, Fissidentalium with numerous regular, fine longitudinal ribs. The white shells are robust and no posterior slit on the dorsal aperture was observed in the examined specimens. Most live specimens with shell lengths of 32–63 mm have a sea anemone attached to the concave, anterior surface of the shell. The ventral and dorsal apertures are slightly wider than high. Preserved, unrelaxed soft body dividable into a ventral buccal, a middle gut and a dorsal gonad region (following Shimek and Moreno 1996) and is about 2/3 of total shell lengths. Buccal and gonadal regions are of similar size and each about 3 times longer than the gut region.

Etymology: “aura” means breeze in Latin and used in genitive case. This name refers to the windy conditions during SO286 as well as to the shipping company Briese Research operating RV Sonne.
